The earliest version of Autumnglo was simply shaded brown. The middle clear areas on most of these old guitars have yellowed, but wasn't originally apparent. The next version was just Fireglo laid on rather heavily. The last version was back to that original brown, but in a satin finish, while the gloss version of that color was designated Walnut.

So when someone says Autumnglo, you always have to ask "WHICH Autumnglo"?"
